Secured Key Agreement Schemes in Wireless Body Area Network — A Review

Objective: To review different key agreement schemes which are used to establish Wireless body area network (WBAN) on the basis of identified attacks and also evaluate performance parameters. Method: In this paper, an overview WBAN, its architecture, difference between WSN IEEE 802.15.6 specifications in environment security essentials discussed at first. It further divides into four classes provides extensive distinct parameters viz. data confidentiality, node authentication, integrity, mutual unforgeability, unlinkability, forward/backward secrecy, scalability, freshness, dos attack capture attack. Schemes searched using keywords- (“Traditional Key Agreement Scheme” OR “Physiological “Signal Based “Hybrid “Security Scheme”) AND (“Wireless Body Area Network” “WBAN” “Body “BAN” Sensor “BSN” “Medical “MBAN”). The papers shortlisted around long stretches 2003-2021 with a focus recent work from Xplore, Springer, Science Direct, ACM, MDPI Google Scholar databases. analyzed against mentioned result comparative analysis is shown tables chart tools graphically. Findings: wide coverage in-depth exposure shortcomings listed will provide road map researchers develop secure future. Moreover, maximum do not consider all three aspects memory efficiency, computational efficiency energy foremost resource scarce WBAN. Novelty: This unique as it analyzes under specific found literature while other discuss general threats corresponding counter measures WBAN environment. management missing works.
